### Question: What causes Acoustic neuroma?
### Response: Acoustic neuroma seems to be a genetic disease that means it’s existance came from malfunctioning of a specific gene on chromosome 22. Naturally, this gene produces some proteins to regulate Schwann cell, covering nerves growth but due to some unknown reasons this gene become corrupted and its function as a Schwann cell growth regulator disturbed so they can grow uncontrollably and form a tumor. This gene malfunctioning can also come from a rarely genetical disease called Neurofibromatosis type II, that is responsible for two sided tumor.
